Final answer:
A refresher course is not determined by how long you have been inactive. It is designed to review and reinforce previously learned material.
Step-by-step explanation:
A refresher course is not determined by how long you have been inactive. Rather, a refresher course is designed to review and reinforce previously learned material. It is often taken to help individuals regain knowledge and skills that may have diminished due to a period of inactivity or lack of practice.
For example, let's say you haven't taken a math class for several years and want to brush up on your skills before taking a more advanced mathematics course. You might choose to enroll in a refresher course to review the foundational concepts and strengthen your understanding.
In summary, the duration of inactivity does not determine the need for a refresher course. It's a personal decision based on an individual's desire to reinforce their knowledge and skills in a particular subject.
